How it works

From idea to app
in three steps

01
Describe your app
Tell appslapper what you want to build in plain English. No technical knowledge required — just describe the idea.
02
AI writes the code
appslapper generates a complete, working application — frontend, backend, database. Real code, not a mockup.
03
Iterate instantly
See your app live in a preview. Ask for changes in chat — appslapper updates the code and refreshes the preview.
Features

Everything you need
to build faster

appslapper handles the full stack — from UI to database — so you can focus on what matters.

Live preview
Your app runs in a real Docker container. See it live as you build — no setup, no deployment needed.
Persistent database
Apps come with SQLite built in. Data persists across sessions — your users' data is always there.
Auth built in
First-party login and Google OAuth work out of the box. No credentials to set up — just ask for it.
AI inside your apps
Build apps that use AI themselves. appslapper injects a proxy so your apps can call GPT-4 without any API keys.
Version history
Every AI edit is saved as a snapshot. Made a mistake? Roll back to any previous version instantly.
Export anytime
Download your full project as a zip at any time. Your code, your files — no lock-in.
